Dec 1, 2017 · (sin70° +cos40°)/(cos70°+sin40°) We can start by using the following trigonometric identities: sin (a + b) = sin a cos b + cos a sin b. cos (a + b) = cos a cos b - sin a sin b. Let's rewrite the numerator and denominator using these identities: sin 70° + cos 40° = sin (70° - 50°) + cos 40° = sin 70° cos 50° - cos 70° sin 50° + cos 40°

Sep 14, 2017 · Given, A trigonometric equation sin70°cos10°-cos70°sin10°=√3/2. To Prove, The value of sin70°cos10°-cos70°sin10°=√3/2.

To find---> Cos10° Cos50° Cos60° Cos70° Solution---> We have an identity, 2CosA CosB = Cos( A + B ) Cos( A - B ) Cos10° Cos50° Cos60° Cos70° Multiplying and dividing by 2, we get, = ( 2 Cos70° Cos 50° ) Cos10° ( 1/2 ) / 2 = {cos( 70° + 50° ) + Cos( 70° - 50° )}Cos10° / 4 = ( Cos 120° + Cos 20° ) Cos10° / 4
